ECSE Departmental Research Seminars

Speaker: Ned Karim

E&CSE, Monash University

Abstract:

The research area is the investigation of the distribution of electrical energy around a large ship using DC type electrical reticulation rather than the more conventional AC type system. This concept represents a major advance in the way electrical energy can be distributed to load systems, and is currently attracting considerable research interest. It is particularly applicable to situations where the loads include a substantial percentage of power electronic conversion systems, such as in the case foe a large ship. However, as correctly identified by the researcher, little research work has been reported regarding the operation of this type of network, particularly in terms of the reticulation system’s stability under dynamically changing load and generation conditions. This seminar reports a study of the dynamic behaviour of DC Bus power systems fed by multiple alternators with single and multiple rectifiers. Obtained simulation results from a ship DC power network are used to validate the proposed method.

About the speaker:

Ned received his B.Sc. degree in Electrical & Electronic Engineering (1976), a postgraduate diploma in programmable electronics from the University of kent at Canterbury (1981) and M.Sc. by research from the University of Bath, UK (1983).

He has many years of diverse experience in the field Engineering. This has been gained from working extensively in Industries like Caltex, Indonesia, Nilsen Electrical Industries, Victoria, Cyphalok Security Manufacturing, NSW and Fenwood Designs Ltd, UK & a variety of higher education institutions like Singapore Polytechnic, Open university, Edith Cawan university, Constantine University in North Africa and some other technical institutions in China and the Middle East.

During this time he has established strong links and memberships with professional bodies. He has served in professional organisations in various capacities, among which are:

Senior member of IEEE

Chairman of the Industrial Electronics Chapter from 1997 to 2001, IEEE Singapore Section

IEEE Executive Section committee member

Co-Chair and Auditor of IEAust, Singapore group.

Committee member and organiser of the International Conference on Power Electronics & Drive Systems (PEDS)

Reviewer of some papers in IEEE Journal of Power Engineering

He has been listed in Who's Who in the World.
